• Immediately turn the power off, remove the AC
adaptor from the outlet, and request servicing by
your retailer, the nearest Roland Service Center,
or an authorized Roland distributor, as listed on
the "Information" page when:
• The AC adaptor, the power-supply cord, or the
plug has been damaged; or
• If smoke or unusual odor occurs
• Objects have fallen into, or liquid has been
spilled onto the unit; or
• The unit has been exposed to rain (or otherwise
has become wet); or
• The unit does not appear to operate normally
or exhibits a marked change in performance.
..........................................................................................................
013
• In households with small children, an adult
should provide supervision until the child is
capable of following all the rules essential for the
safe operation of the unit.
..........................................................................................................
014
• Protect the unit from strong impact.
(Do not drop it!)
..........................................................................................................
015
• Do not force the unit's power-supply cord to
share an outlet with an unreasonable number of
other devices. Be especially careful when using
extension cords—the total power used by all
devices you have connected to the extension
cord's outlet must never exceed the power rating
(watts/amperes) for the extension cord. Excessive
loads can cause the insulation on the cord to heat
up and eventually melt through.
..........................................................................................................
016
• Before using the unit in a foreign country, consult
with your retailer, the nearest Roland Service
Center, or an authorized Roland distributor, as
listed on the "Information" page.
..........................................................................................................
022b
• Always turn the unit off and unplug the AC
adaptor before attempting installation of the
circuit board (DIMM; p. 140).
..........................................................................................................
023
• DO NOT play a CD-ROM disc on a conventional
audio CD player. The resulting sound may be of a
level that could cause permanent hearing loss.
Damage to speakers or other system components
may result.
..........................................................................................................
101b
• The unit and the AC adaptor should be located so
their location or position does not interfere with
their proper ventilation.
..........................................................................................................
102c
• Always grasp only the plug on the AC adaptor
cord when plugging into, or unplugging from, an
outlet or this unit.
..........................................................................................................
103b
• At regular intervals, you should unplug the AC
adaptor and clean it by using a dry cloth to wipe
all dust and other accumulations away from its
prongs. Also, disconnect the power plug from the
power outlet whenever the unit is to remain
unused for an extended period of time. Any
accumulation of dust between the power plug
and the power outlet can result in poor insulation
and lead to fire.
..........................................................................................................
104
• Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be
placed so they are out of the reach of children.
..........................................................................................................
106
• Never climb on top of, nor place heavy objects on
the unit.
..........................................................................................................
107c
• Never handle the AC adaptor or its plugs with
wet hands when plugging into, or unplugging
from, an outlet or this unit.
..........................................................................................................
108b
• Before moving the unit, disconnect the AC
adaptor and all cords coming from external
devices.
..........................................................................................................
109b
• Before cleaning the unit, turn off the power and
unplug the AC adaptor from the outlet (p. 18).
..........................................................................................................
110b
• Whenever you suspect the possibility of lightning
in your area, disconnect the AC adaptor from the
outlet.
..........................................................................................................
115a
• Install only the specified circuit board (DIMM).
Remove only the specified screws (p. 140).
..........................................................................................................
118a
• The screws that hold the card protector in place,
the screws that are removed from the bottom
cover when expanding the memory, and the
grounding screw should be kept in a safe place
out of the reach of children so that small children
will not accidentally swallow them.
